MECHANICAL MOTOR.

' SPECIFICATION forming part of Letters Patent No. 388,416, dated August 28, 1888.

Application filed May 29, 1888. Serial No. 275,437. (No model.)

To all whom it may concern:

Be it known that I, PLEASANT HOOKETT, a citizen of the United States, residing in Stafford county, Kansas, have invented new and useful Improvements in Mechanical Motors, of which the following is a specification.

The primary object of my invention is to provide improved apparatus for propelling vehicles; but my object is also to provide an apparatus for various kinds of machinery for transmitting and multiplying power.

In the accompanying drawings, illustrating my invention, Figure 1 is a side view, Fig. 2 a top plan view, and Fig. 3 a section on the line 3 3 of Fig. 2.

While I have illustrated in the drawings my invention as applied to a vehicle, I wish it understood that some features of the invention may be applied to various kinds of apparatus. I will, however, limit the description of the invention to a vehicle, as shown in the accompanying drawings.

Referring now to the drawings, A indicates the vehicle-body; B, the main carrying-wheels, rigidly secured to an axle, O, journaled in suitable bearings, D, at the rear end of the vehicle-body.

E E indicate cranks or eccentrics on the axle, on opposite sides thereof, and preferably arranged midway between the wheels. vehicle-body is cut away at F to permit the proper movement of the cranks E.

G indicates a standard, preferably extending along the longitudinal central line of the vehicle-body from front to rear.

HI-I indicate the driving-wheels, which are shown as cog-wheels arranged on opposite sides of the standard G at its front end and journaled in suitable bearings, I.

J indicates a small cog-wheel or pinion journaled in the standard at y and arranged to gear with one of the cog-wheels H. The cogwheels H are rigidly secured together, as shown. Two pinions may be used, if desired, one for each of the driving-wheels H. y

'K is a crank secured to the pinion J, by which it may be turned. As the pinion is revolved the motion will be imparted to the cog- Wheels H. Instead of applying the power by a The crank, it may be applied by a belt or in other suitable ways.

L L indicate pitman-rods secured to the eccentrics E. At their upper ends the pitman-rods are hinged to the shorter arms of the driving-levers M, which are pivoted to the standard Gat g. The ends as of the leverarms are attached to the driving-wheels H by means of wristpins N, which project through slots 0 in the levers M and are free to slide therein when the driving-wheelsI'I are revol ved. The wrist-pins N are preferably made adjustable in radial slots 1?, formed in the driving-wheels H. The wrist-pins are pro vided with flanges or collars a between the driving-levers M and the driving-wheels H, and with adjustable nuts for securing them to the driving-wheels H. By this organization a of apparatus power applied to the pinion J will be multiplied by the larger drivingwheels H, and the power transmitted by the driving-wheels H to the longer arms of the driving-levers M will be multiplied by the levers M when transmitted to the pitman-rods L, so that comparatively small power applied to the crank or pinion J may be snfficient to overcome heavy loads;

R indicates the caster-wheel for supporting the front end of the vehicle-body. I have merely shown such a wheel as one way of supporting the front end of the vehicle. It will of course in most cases be desirable to use an axle with a pair of wheels at the front end of the vehicle as well as at the rear end.

My improvements are especially applicable to hand-cars; but they may be applied to all kinds of vehicles, and also to various kinds of apparatus in which it is desirable to transmit and multiply power.

I claim as my inve11tion-- 1. The combination of the driving-wheels, the driving-levers, the pitman-rods hinged to the shorter ends of the driving-levers, and the wrist-pins secured to the driving-wheels and adapted to slide in slots in the ends of the longer arms of the driving-levers, substantially as set forth.

2. The combination of the vehicle-body, the wheels, the axle rigidly secured to the wheels,

the cranks on the axle, the standard on the In testimony whereof I have hereunto subvehicle-body, the driving -wheels mounted scribed my name. thereon, the driving-levers, the pitman-connections between the driving-levers and the PLEASANT HOGKETT. 5 cranks on the axle, and the wrist-pins extending through slots in the longer arms of the Vitnesses:

drivinglevers for connecting the levers to the \VILLIAM B. 0012, J

driving-wheels, substantially as set forth. FRANCIS M. GoIN.
